In this article, we calculate the contributions of the vacuum condensates up to dimension-6 in the operator product expansion and study the masses and decay constants of the heavy tensor mesons ,
,
,
using the QCD sum rules. The predicted masses are in excellent agreement with the experimental data, while the ratios of the decay constants
, where the exp denotes the experimental value.
